• Hands on Linux sandbox with namespaces and cgroups

# ls /sys/fs/cgroup/

# mkdir /sys/fs/cgroup/memory/group0

# echo $$ > /sys/fs/cgroup/memory/group0/tasks

# echo 1M > /sys/fs/cgroup/memory/group0/memory.limit_in_bytes
  или
# echo 512K > /sys/fs/cgroup/memory/group0/memory.limit_in_bytes

# vim anyfile
